Stemcell Release Notes

This topic provides an overview of the Stemcell versions used by VMware Tanzu Network.

A stemcell is a versioned OS image that BOSH uses to create VMs for the BOSH Director, VMware Tanzu Application Service for VMs (TAS for VMs), and other Service tiles such as VMware Tanzu SQL [MySQL]. For more information, see What is a Stemcell? in the BOSH documentation.

Stemcells are available for download on VMware Tanzu Network. Once downloaded, you can upload them to your deployment using the Stemcell configuration pane of a given tile or by navigating to the Stemcell Library page in Ops Manager.

Before you upgrade Ops Manager, always verify that all installed tiles are compatible with the version of Ops Manager that you are deploying and its supported stemcells. For more information about Ops Manager and stemcell compatibility, see Review Service Tile Compatibility in the Upgrade Preparation Checklist.

To discover which stemcell version is used by which tile version, review the release notes or the VMware Tanzu Network download page for the tile.

NOTE: Manual stemcell creation has been deprecated. Use stembuild v2019.23 or later to create stemcells automatically. For more information, see Creating a Windows Stemcell for vSphere Using stembuild.
